BMW 325i fuel - unleaded or not?

[Colin Barratt]

I have always assumed that the 1991 Pre Vanos M50/B25 325i engine in my Sportster would have been built to run on unleaded fuel. Am I correct?
I can't find a definitive answer on the net - what do you think? Should I use an additive anyway?

The M50 is a more modern engine than my M20B25 I have in Vikki, and she's only ever had a unleaded diet. I think you'll be fine with out it.

Hi Colin,

My Sportster has been on the road since 2005 and I have never used an additive. She runs fine without it.

Regards.
